In white dwarf we have mention of the release of the Venom. This is excellent news. I was concerned we would be forever without, however Jes has mentioned that it looks like we will get our venom. While it is not an official release of information or a release date, I take it as concrete.
Here is what was said during a conversation about Raiders between Andy and Jes. This is from the new White Dwarf.
"When the Venom (another light and fast dark eldar transport) is eventually made I plan to have Wyches hanging from that, and they'll be interchangeable with the Raider allowing you to swap clinging passengers between the two vehicles."
What they mean is that the warriors on the Raider model that can hang, are easily removed (no glue required), so that you can show a loaded raider and an empty one. When the Venom is released it will have wyches. Very exciting.
It doesn't mean we have a model being worked on right now, but at least it is in their minds to do one.
